Secca dell'Ammiraglio is a Gulf of Asinara boat dive on the northeast face of a small islet, where a shoal runs into a submerged canyon and a reef wall packed with Mediterranean life. It is a photographer-friendly route with a classic Sardinian rock profile and enough structure to stay interesting for divers who are comfortable with boat timing and careful buoyancy.
